Los Angeles is now largest city in America with $15 minimum wage

It's official: Los Angeles is now the largest city in America to guarantee workers at least $15 an hour.

Mayor Eric Garcetti on Saturday signed into law a bill raising the minimum wage from $9 an hour to $15 over the next five years. The move was expected after city council had passed the legislation by a near unanimous vote.

The minimum wage is already set to increase to $10 per hour across California in 2016.

And the state Assembly is considering another statewide wage hike: A bill that passed the state Senate recently would bring the rate to $13 per hour by 2017.

In Los Angeles, several groups representing restaurants, theater owners and small businesses opposed the change.
